The development of this turbofan engine from Tianfeng Technology Company has been in an orderly manner. The comprehensive and detailed design stage has entered its peak period. Many key and key components have been designed one after another.

This is the first turbofan engine of Tianfeng Technology. Li Tianfeng attaches great importance to the design of key components and key components. Li Tianfeng personally checks it.

Technology Center, Aero Engine Design Institute.

As the chief designer of this turbofan engine, Sun Xiaoping was presided over the meeting. The designers of the compressor part were all in the conference room because the discussion was about important components of the engine, and Li Tianfeng also attended the meeting.

On the projector, the 3D color picture of the compressor part is projected on the screen. Everyone present can clearly see that although this turbofan engine can only be regarded as a medium-sized turbofan engine, it is extremely advanced in design and uses many very advanced design technologies. For example, the design used by the compressor part is an advanced load compression system.

The goal of the development of high-pressure compressor technology is to have a high pressure ratio, a small number of stages, a high thrust-to-weight ratio, and good flight performance. The compressor part of this turbofan engine of Tianfeng Technology uses a high-load compression system.

Among them, low aspect ratio design, pneumatic forward sweep design, overall blade disc, overall blade ring, compressor stability active control and other technologies are representative new technologies in advanced load compression systems.

The low aspect ratio blade is a wide string blade. Compared with the narrow string blade, it widens the chord length, shortens the length of the compressor, improves the ability to resist external damage, fatigue resistance and stall margin. It can also reduce the number of compressor parts and reduce production and manufacturing costs.

The fan blades of this turbofan engine are designed with hollow titanium alloy wide string blades, and the design has been completed. The fan blades have entered the trial production stage.

The compressor blades also use wide string blade design, and the overall titanium alloy wide string blades. This type of compressor blades are widely used in large bypass ratio turbofan engines and high thrust-weight ratio small bypass turbofan engines. Ge company's teh56 technical plan verification machines and 119 engines and ej200 engines use this wide string blade.

Such blade design is also very advanced internationally, and it is definitely the first to be found in China.

Sun Xiaoping said loudly: "Our compressor part has basically completed the preliminary design. Now let's get together to brainstorm and discuss the design of the compressor part, especially the design of some key parts."

After Sun Xiaoping finished speaking, the picture on the projector turned around and appeared in front of everyone. The first-stage compressor blades were the largest and the longest, and the subsequent step by step became smaller and shorter.

The blades of the first-stage compressor are very important and have extremely high design technical content. Sun Xiaoping introduced the design of this blade based on the design drawings of this blade.

"This is our first-stage compressor blade, the overall titanium alloy wide string blade design adopts the most advanced and most reasonable pneumatic and structural performance design..."

Sun Xiaoping's introduction was very detailed, and Li Tianfeng listened carefully. He also looked at the design drawings carefully, and even picked up the draft paper and pen, calculated it, wrote it, and drew it, and from time to time. Li Tianfeng frowned and thought about it.

This kind of blade only completes the preliminary design, so there will definitely be some problems. After Sun Xiaoping introduced it, many designers present expressed their opinions. A small number of people even pointed out some shortcomings and minor problems in blade design.

Sun Xiaoping signaled the two supervisors next to him to record all these things one by one, and then combined them to design and improve them based on these issues.

Everyone's speeches were very active and enthusiastic. Such meetings and speeches have almost become a tradition of Tianfeng Technology. You can speak freely without any scruples. If you say it right, you will be adopted. If you say it wrong, it doesn't matter.

Everyone has said a lot about the design of the compressor blades. There are even two designers who argued fiercely at the meeting because of the controversy in the design issues, with red faces and thick necks. Such controversy over design issues is completely allowed.

After discussing for 20 or 30 minutes, everyone basically said it all. Sun Xiaoping said: "Mr. Li, please say a few words to correct our shortcomings in design."

Sun Xiaoping admires Li Tianfeng's design level very much. The designers of the design institute also admire Li Tianfeng's design level very much. In everyone's mind, Li Tianfeng is the highest existence in everyone's heart!

Everyone looked at Li Tianfeng and waited for Li Tianfeng to speak. Li Tianfeng smiled slightly and said loudly: "The design of this compressor blade is generally good. It fully grasps the essence of the wide string blade design, but there are still some slight shortcomings. These aspects need to be improved, such as the coordinate size of the blade shape needs to be improved in this way..."

Li Tianfeng pointed out the shortcomings in the leaf design one by one, and Sun Xiaoping quickly recorded them one by one. There were some places that Sun Xiaoping himself did not see any shortcomings or problems. Sun Xiaoping admired Li Tianfen's point of view. He deserved to be Mr. Li. His design level is really high.

Low-pressure compressor: level 4. High-pressure compressor: level 5. Everyone discussed the blades of the compressor one by one, and a lot of problems were collected. After the meeting, the design will be improved and improved.

Low aspect ratio blades have become the key technology of advanced aero engine compression systems. Combined with 3D aerodynamic sweeping, hollow structure, overall blade structure and lighter titanium-based composite materials technology, it is the focus of future development.

This turbofan engine of Tianfeng Technology Company uses the overall overall blade structure of titanium-based composite material, which is very advanced in design.

The above-mentioned wide-string compressor blades and titanium-based composite compressor roulettes are made of bonding process, and their weight is only 30% of the drum structure of conventional metal material.

Such a design not only meets the requirements of high speed and high temperature, reduces the quality of the disk, but also reduces manufacturing costs and improves maintenance.

Such a design has a high technical content. It was originally a design sketch given by Li Tianfeng himself. Combined with Li Tianfeng's design sketch, the design team led by Sun Xiaoping carried out detailed designs. Now, the preliminary design has been completed, everyone is going to discuss and review such a design together.

Sun Xiaoping personally introduced the design of the overall Ye Pan. After the introduction, everyone followed the convention and pointed out some shortcomings in the design one by one. Finally, Li Tianfeng also spoke and pointed out some key points.

Combining these issues, after design improvement and improvement again, the design will be basically mature. Finally, Li Tianfeng will definitely check it personally again.

After recording these questions, Sun Xiaoping said with some concern: "Boss, will there be any problems with our titanium-based composite materials?"

Li Tianfeng waved his hand and said, "Don't worry about this. Our Materials Engineering Technology Center is conducting research on this new material. It has already achieved initial results and will not delay the development of this engine."

After thinking for a while, Li Tianfeng said: "However, because it involves new materials, new designs, completed designs, and trial production of parts, we must conduct strict low-cycle fatigue rotation tests, and conduct sufficient tests and verifications before we can install our engine."

Sun Xiaoping nodded and said, "Boss, we must not relax in this regard. We must have gone through a strict low-cycle fatigue rotation test and we will officially install the machine after the test is fully qualified."

The meeting lasted a whole day, from morning to afternoon, and the compressor part of this turbofan engine was fully discussed. Sun Xiaoping collected many questions and will combine these issues to improve and improve the design of this advanced load compression system.

This turbine engine is very advanced in design. Not only does the compressor part adopt the design of a high-load compression system, but the combustion chamber part also adopts a high-thermal load combustion chamber design, and the turbine part adopts a high-load turbine design, etc.

Li Tianfeng has great hope for this engine.

So many advanced design technologies have been adopted in the design, involving a lot of new materials and new technologies. When processing and manufacturing parts in the future, many new process technologies will be adopted.

Tianfeng Technology Company has carried out the design of this engine in an orderly manner and has carried out detailed designs in full swing. Some parts have even been designed and have begun to enter the trial production stage, such as the fan blades mentioned above.

Linhai Technology Company.

With the powerful injection of hundreds of millions of funds from Tianfeng Technology Company and the "Li's Technique" provided by Tianfeng Technology Company, which represents the highest and most advanced technology level, the entire Linhai Technology Company has been rejuvenated.

Zhao Linhai was in his office, looking at a bearing made by the "Li's craftsmanship" with great enthusiasm, and even looked very carefully with a magnifying glass.

The chief engineer of Linhai Technology Company next to him said with emotion: "Mr. Zhao, Tianfeng Technology Company is really amazing. The 'Li's process' provided is very advanced. We basically tested the vacant process parameters in just over a month."

Zhao Linhai nodded and said, "I think this bearing is made according to the Li's craftsmanship method. I think it's very good. An insider can find that it is much more refined than ordinary bearings at a glance. I will arrange the test and test immediately and form a detailed report on the test and test of this bearing. I want to send it to Mr. Li in person."

Seeing his chief engineer walking out of his office with this bearing, Zhao Linhai was full of gratitude to Li Tianfeng. Without Li Tianfeng, there would be no vitality of Linhai Technology Company.

Relying comfortably on his boss' chair, Zhao Linhai thought to himself that with such advanced bearing processing technology, Linhai Technology Company will do a good job.

"Dong, dun, dun!"

Hearing the knock on the door outside, Zhao Linhai said in a pride: "Please come in!"

Seeing the person coming in, Zhao Linhai's eyes froze and asked in a deep voice: "Is it you?"
